СПОСОБ ИЗГОТОВЛЕНИЯ ТЕРМОИЗОЛЯЦИОННЫХ ПЛИТMETHOD OF MAKING THERMAL INSULATED PLATES
1one
Известен способ изготовлени термоизол ционных плит из древесной массы на св зующем сапропеле методом холодного прессовани с последующей сушкой.A known method for the manufacture of thermo insulating slabs of wood pulp on a binding sapropel by cold pressing followed by drying.
Цель изобретени - ускорить процесс сушки плит и улучщить их качество.The purpose of the invention is to accelerate the process of drying plates and improve their quality.
Достигаетс , это тем, что издели после прессовани выдерживают в термокамере в течение 5-6 час при 160-180°С, а затем в течение 3-6 дней при 40-50°С.This is achieved by the fact that the products after pressing are kept in a heat chamber for 5-6 hours at 160-180 ° C, and then for 3-6 days at 40-50 ° C.
Заполнитель в виде дробленых древесных отходов со св зующим-сапропелем влажностью 85-90% - и антисептиком прессуют под давлением 3-10 кг/см. После прессовани плиты в преосформах подвергают термообработке в термокамере в течеаие 5-6 час при 160-180°С, а затем в течение 3-6 дней при 40-50°С.The filler in the form of crushed wood waste with a binder-sapropel with a humidity of 85-90% - and an antiseptic is pressed under a pressure of 3-10 kg / cm. After pressing, the plates in preforms are heat treated in a heat chamber for 5-6 hours at 160-180 ° C, and then for 3-6 days at 40-50 ° C.
Физико-механические показатели полученных плит следующие:Physico-mechanical properties of the plates obtained are as follows:
Водопоглощение, %45Water absorption,% 45
Прочность на изгиб, кг/см 10Bending strength, kg / cm 10
Прочность на сжатие, кг/см 12Compressive strength, kg / cm 12
Коэффициент теплопроводности при 3,7% влаги, KKuJijM час, град.0,0703Thermal conductivity coefficient at 3.7% moisture, KKuJijM hour, deg.0.0703
Предмет изобретени Subject invention
Способ изготовлени термоизол ционных плит из древесной массы на св зующем сапропеле методом холодного прессовани с последующей сущкой, отличающийс тем, что, с целью ускорени процесса сушки и улучшени качества .плит, издели после прессовани выдерживают в термокамере в течение 5-6 час при 160-180°С, а затем в течение 3-6 дней при 40-50°С.A method of manufacturing heat insulating slabs from wood pulp on a bonding sapropel by cold pressing with subsequent resin, characterized in that, in order to speed up the drying process and improve the quality of the plates, the product after pressing is kept in a heat chamber for 5-6 hours at 160 180 ° C, and then for 3-6 days at 40-50 ° C.
